Benchmarks Of The Official KQ ZFS Linux Module

"Last summer we delivered the news that a native ZFS file-system
implementation for Linux was coming by an Indian company known as
KQ Infotech where they leveraged the Lawrence Livermore National
Laboratories ZFS Linux code, finished it off in some areas, and
took care of the POSIX support. This ZFS Linux module was
eventually released to a group of beta testers -- us included --
and we ran some ZFS Linux benchmarks back in November using the
latest beta code. Since that point, however, KQ Infotech has made
their ZFS Linux port publicly available and earlier this month they
declared this work as stable via its general availability release.
We have decided to benchmark this latest ZFS Linux code to see
where the performance now stands against the EXT4, Btrfs, and XFS
file-systems.

"KQ Infotech now hosts their source trees for their ZFS work
publicly on this GitHub page with the ZFS kernel module, LZFS (the
ZFS POSIX layer for Linux), SPL (the Solaris Porting Layer for
Linux), and their miscellaneous scripts for building packages.
Behind their registration wall on the KQ Infotech web-site you are
able to download their official binaries that have compiled
packages for Red Hat Enterprise Linux 6, Fedora 14, Ubuntu 10.04
LTS, and Ubuntu 10.10. The 64-bit versions of these Linux
distributions are required as well as using specific kernel
versions (2.6.32-71.el6, 2.6.35.10-74, and 2.6.35-22-server)."
